To alliwhom it may concern-r Be: it known that 1,;ERNEST Ea -nearer, acitizen'of' the United? States, residing at New York, in the county' ofNew York and! State of New York, have invented anew and use; fulImprovement: 'in Wick Raising'Devices for Lamps: and Lanterns, of whichthe fol lowing' is a specification.

This invention relates: to vehicle; lamps and lanterns ofthat type inwhich therlamp is incliosedr within and is removable from the lamp orlantern casing ndsparticularly to improvements in wick raisingmechanismsfor such lamps and lanterns.

The object of the invention is to provide such lamps and lanterns-with:a wick raising mechanism of simple and practical construe tion, by meansof which; the wick can be readily adjusted as required',and which willserve as alocking' means for. retaining the lampin the casing and yetwill allow the lamp to readily removed from and replaced in properposition in the. casing;

1 represents the lamp casing which is provided with a burner chamber 2,and below the same with a base chamber 3, in which the oil font 4: isinclosed and supported. The base chamber communicates at its open upperend with the burner chamber, and the lamp, consisting of the oil. fontland burner 5, is adapted to be placed in position 1n the base chamber 8and to be removed from the casing preferably through the burner cham-Specification of Letters Patent.

ber,,w-hiich= is provided at the front. or otherat one side of the wicktube 8 thereof, and

islprovided; with one or more toothed wheels Q'wh-ich extend into thewich tube" and are adapted-to engage the wick for raising and loweringthe same. 10: indicates a handle of'any suitable kind onthe lamp forfacilitating the insertion andiremova l of the lamp to and from thecasing.

The parts as thus far described may be of any usual or suitable.construction.

The wick raising shaft 7 whichis jour na led on thelamp burner and isremovable with the lamp from thelialnp casing isoperated by a shaft 11which is journa'led on the lamp casing and is adapted" to be: con nectedwith the. shaft 7 for turning: the same by cooperating"clutch orcoupling: members 12 and 13, secured respectively to the adjacent endsof the shafts: 7 and r1; These clutch'members maybe of any suitable construction adapted to be readily engaged to cause the'shaftsto turntogether even should the'shaft's be more or less out of alinement', andto be readily disengaged by pulling the operating shaft 11 outwardly fordisconnectiin the shafts to permit the" removal" of the lamp! from the:casing; The clutch mom ber's shown are: provided? with peripheral teethadapted to interlock'with-each other. The operating shaft 11 passesthrough a spring barrel 1%, which is secured to. and projects outwardlyfrom tlie'lamp casing, and a springlasurrounding the shaft: 1 1' inthespring barrel between the outerend' of the barrel and the clutchmember 13 tends to move" the shaft 11. inwardly" and: interlock theclutch member 13 thereon with the cooperating clutch member 12 on theother shaft 7. When the clutch members are interlocked, the wick-raisershaft can be 0perated for raising and lowering the wick by turning theoperating shaft 11 by means of a thumb wheel or button 16 at the outerend of the operating shaft 11. The lamp cannot be conveniently removedfrom the casing while the shafts 7 and 11 are in operative engagement,owing to the interlocking of their clutch members 12 and 13, and thelllltl wick-raising mechanism thus serves as a lock to retain the lampin the casing. WVhen it is desired to remove the lamp from the lampcasing, the operating shaft 11 is pulled outwardly by means of its thumbwheel or button to disengage the clutch members 12 and 13, and the lampcan then be lifted out of the chamber-'2 and removed from the casing. ar

In order to facilitate the removal and replacing of the lamp, theoperating shaft 11 is provided with one or more lateral projections,conveniently formed by a cross pin 17 extending through the shaftadjacent'to its outer end, and the outer end of the spring barrel isprovided with lateral slots 18 through which this pin is adapted to passwhen the shaft llis turned to a position to cause the pin to registerwith the slots. By pulling the operating shaft outwardly until the crosspin passes through the slots and thenturning the shaft a part revolutionto throw the pins out of registrationwith the slots 18, the pin willbear against the outer end of the barrel and hold the shaft in its outerposition in which the clutch members are disengaged; When the shaft isthus held in its released position one clutch member cannotengage theother and interfere with the easy positioning of the lamp in and itsremoval from the casing. After placing the lamp .in position in thecasing the operating shaft can be released and readily. engaged with thewick-raising shaft7u .The lamp and lamp casing are provided with partsadapted to be engaged with each other when placing the lamp in thecasing to insure of the lampbeing properly positioned with thewick-raising shaft 7 in alinement with the operating shaft 11. As shown,the lamp is provided at its upper front portion, preferably beneath thehandle 10, withta lug or projection 20 adapted to enter a. seat 21 in.thecasing at the lower edge of the door opening 6. The lug and seat:arein an exposed position, and in placing the lamp in the. casing thelug can be readily engagedin the seat and when thus placedthewicksraising shaft will be in alinement withfithe operating shaft, soas lock to couple said shafts together, and a spring acting on saidoperating shaft to holdsaid clutch membersin operative engagement, saidoperati ngshaftbeing movable endwise to disengage said clutchimembersand permit the removal of the lamp, and means acting whensaid operatingshaftis moved to a given position to hold the operating shaft uncoupledraising shaft.
